The current conflict between Spain and Catalonia explained
Spain is a state split into autonomous communities, three of which—Catalonia, Galicia, and Basque Country—are denominated historic communities, having their own languages that coexist co-officially with Castilian, the official language of Spain. All the autonomous communities in Spain have their Statutes of Autonomy, the basic institutional legislation for an autonomous community, recognized by the Spanish Constitution of 1978.
